IMPROVEMENT IN GRAIN CLEANING AND SCOURING MACHINES.

Specification forming part of Letters Patent No. 201,300, dated March 12, 1878; application filed December 19, 1877.

To all whom it may concern:

Be it known that I, JOHN H. TEAHL, of Reading, in the county of Berks, and in the State of Pennsylvania, have invented certain new and useful Improvements in Grain Separator and Polisher; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my machine'consists in the construction and arrangement of a grain cleaning and polishing machine, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which Figure 1 is a rear elevation of my machine. Fig. 2 is a central vertical section of the same. Fig. 3 is a horizontal section on the line 00 m, Fig. 2. Fig. at is a horizontal section of the grain-cylinder. Fig. 5 is a detailed view of one of the polishing-plates.

The frame of the machine consists of four upright corner-posts, AA, connected near their lower ends by a spider, B, a suitable distance above said spider by a plate, 0, which forms the bottom of the grain-cylinder, and in the upper part by the fan-case E, the plate 0 and fan-case E having suitable arms or projections to connect with the corner-posts.

In the center of the spider B is a step, a, in which rests a vertical shaft, 1), to which the grain-polishing devices are attached, as also the fan D, which latter operates within the fancase E.

Upon the plate (3 is placed a cylinder, made of cast-iron, of a series of sections, H, having flanges at the ends to overlap each other, and covered by a top plate, 1 which is fastened to the plate 0 by bolts or other suitable or convenient means, so as to clamp and hold the sectional cylinder firmly between the two plates.

The sections H, which form the cylinder, are formed with vertical corrugations e, as shown, and have also a central horizontal rib or flange, 01, extending inward, so that when the cylinder is put together there will be formed a continuous flange, at or about the center, around the inside of the cylinder.

In the center of the plate 0, around the shaft b, is an opening, f, for the admission of air,

and in the center of the top plate I is a similar opening, provided with a tube, h, which leads to the bottom plate of the fan-case, and communicates with the interior thereof.

Within the cylinder H, tothe shaft b, are secured two horizontal circular plates, J J, one of which is located above the flanged of the cylinder, and the other in the bottom of the cylinder, but slightly elevated from the plate 0. Each of the plates J is provided at its outer edge with a series of upwardly-extending projections, K K, equidistant from each other. These projections have each avertical rounded front edge, k, top end 70 horizontal, and the back'edge Winclined, as shown in Fig. 5, and said projections are not set to coincide with the outer circular edge of the plate J, but are set at an angle, so that the front edge 70 will be farther out from the shaft than the heel or back edge.

On the front of the machine are two vertical air or suction flues,I I, as shown. The flue I is long, and the grain, after passing through the polishing-cylinder, enters said flue near the bottom through a spout or conductor, L, from the bottom plate 0 of the polisher.

The flue I is short, and the grain enters the same at the top, and discharges through a spout or conductor, M, into the polisher through an aperture in the top plate 1 of the polisher. The upper ends of the flues I I open into inclined side flues N and N, respectively, formed between the top of the fan-case and a top plate, 0, secured on the upper ends of the corner-posts A A. The flues N N diverge toward both sides, as shown, and then run parallel to a box, P, attached on the rear end of the machine. This box has at the top three partitions, m,- m, and m, the flues N N entering between the sides of the box and the partitions m m. At the lower end of each parti* tion on is hung a valve, n, upon the outer journal of which is secured an arm or lever, 12,

for turning the valve, and the arm or lever held at any point desired in a rack, R, as shown.

' The lower end of thebox P tapers: to form two discharge-spouts for the screenings the 1 central partition in extending all the way down to; divide the box into such discharge-spouts; 1 fuachof these spouts has an opening art the outside of the :looix, overwhich is hung; a door 1 andgin saiddoori is :a' slide i; to regulate: .:theadmission-ofair, f 1 1 1 1 Theflnes in the:boxP, formed byEthe central "partition m: and the partitions on openat the top into central flue, 1N3 :hetween the 1 two fines N N and from said flue N there is an: opening, s, into the fan-casethrough the? top plate thereof.

1 On top of the machine is a shaki1'1g-Vshoe',=S=, 1 with sieyei'lf, and to this shoe, at the. upper- 1 r 1 end,: is hinged a frame' si with another sieve i 1 T. The hijnging'of the frame Sfallows of the top sieve being easily and quickly raised :for] 1 cleaningthe lower sieve when: required; 1 1 1 1 1 1Ihe shoe S obtains'its shaking motion by f means of a pitman; 1V, eonneeting; the same with a cranlepin on a pnlley5 W, and this pul-i ley is rotated by a belt from a pulley on the shaftb. 1
